+A pseudo-random integer from 0 to 32767, newly generated each time
 this parameter is referenced.  The random number generator
 can be seeded by assigning a numeric value to tt(RANDOM).

+The values of tt(RANDOM) form an intentionally-repeatable pseudo-random
+sequence; subshells that reference tt(RANDOM) will result
+in identical pseudo-random values unless the value of tt(RANDOM) is
+referenced or seeded in the parent shell in between subshell invocations.
